HESI Review

Spermatozoa develop where..?
Seminiferous tubules
What produces testosterone?
Interstitial cells
Where is sperm stored?
What hormone stimulates sperm production
Interstitial cell-stimulating hormone, aka: LH
Where are waste materials in the blood filtered through?
Renal artery
Filtration occurs where?
Glomerulus in Bowman's capsule of nephron
What happens to important nutrients such as water, glucose & ions?
Diffused & reenter the blood
T/F: Is water reabsorbed at the tubules?
Define: Lacteal Vessel
Within villi of intestinal wall.. where fat nutrients are absorbed.
Digests proteins
Digests sugars
Functions of the Liver
1. Stores vitamins & iron
2. Produces bile which aids in digestion
Where is bile stored?
Produced in pancreas, & neutralizes stomach acids
What digests proteins in the pancreas?
Trypsin & chymotrypsin
Hormones of the anterior lobe of Pituitary
(adenohypophysis)- tropic hormones.. act on other endocrine glands
1. Growth hormone
2. Adrenocorticotropic hormone (ACTH)
3. Tyroid stimulating hormone (TSH)
4. Follicle stimulating hormone (FSH)
5. Luteinizing hormone (LH)
Hormones of Posterior Lobe of Pituitary
Oxytocin & ADH
Phagocytic WBCs
Neutrophil & Monocytes
Antibody forming WBC
Location of Tricuspid Valve
Right side
Location of Bicuspid Valve
Left side
Blood is supplied to the myocardium via the..
coronary arteries
Blood drains from myocardium into the ___________ through the __________
Into the Right Atrium through the Coronary Sinus
Follicle stimulating hormone (FSH)--> stimulates to secrete estrogen
Letenizing hormone (LH)--> triggers ovulation, stimulates secretion of progester by corpus luteum, & estrogen, & testosterone
ACTH (adrenocorticotropic hormone)
Released by Ant. Pit., is a gluccocoticoid.
Stress related stimuli such as low blood glucose, fever, physical trauma
Conserves water by decreasing urine volume so more concentrated
Increases BP by constricting arterioles
Steriod, increases blood glucose in response to stress
Hormones produced by adrenal medulla
Epinephrine & Norepinephrine... increase HR, dilate airwayes
Layers of the skin (deep to superficial)
Stratum Basale (Germinativum)
Stratum Spinosum
Stratum Granulosum
*Stratum Lucidum (Soles & Palms)
Stratum Corneum
Sudoriferous glands
Sweat glands
Eccrine sweat glands
Ducts connect to pores.. for thermoregulation
Apocrine sweat glands
Only in axillary & groin..
ducts connect to hair follicles
Ear canal
Ceruminous glands, secretes cerumen
Speacilized apocrine gland
Sebaceous glands
Sebum- oily holocrine secretion.. lubricates skin to prevent drying
Holocrine secretion
Whole cell detaches
Minerals stored in bones
Calcium & phosphorus
Bone forming cells
Maintain bone matrix, mature, fixed
Structural unit of bone
Osteon (aka: Haverstian system)
Concentric circles.. weight bearing
Axial skeleton consists of...
28 bones of the skull
14 facial bones
14 cranial bones
33 vertebral bones
Each muscle cell consists of:
Myofibrils made up of sacrcomeres
Nervous stimulation from motor neurons causes:
release of Ca from sarcoplasmic reticulum which attach to proteins on actin filaments
The Dermis
rests on subcutaneous tissue
Bones of the vertebral column..
7 cervical
12 thoracic
5 lumbar
5 sacral
Hypothalamus regulates..
Body temp, sleep & appetite
Dorsal Horn
where sensory neurons enter spinal cord
Movement of materials from high concentration to low
Subcutaneous tissue
Layer of tissue under the dermis that contains adipose tissue
Coronal plane
Line that divides body anteriorly & posteriorly
movement of nutrients from the digestive tube into the blood stream
Protein making up the I-band of the sarcomere
Special proteins that protect the body from foreign substances
(adenosine phosphate)- energy of the cell
Product of the liver that emusifies fat
Tissue made up of cells & fibers that connect & support
Bodies w/in the nucleus made of DNA & proteins called histones
Functional proteins, their names usually end in ase... regulate chemical reactions in body
Simple sugar. (usuall found in fruits)
Bone to bone
Mucous Membrane
thin sheets of tissue cells that line body openings or canals that open to the outside of the body
Proteins that make up nearly half the proteins in muscle cells
Mucuous membranes vs. Serous membrances
-mucous membranes: line body openings or canals that open to the outside of the body
-serous membranes: line body cavities not having exits to the outside
Connective tissue
Framework for the body- provides structure & support for the organs
Pathway for sperm during ejaculation
vas deferens, ejaculatory duct, & urethra
nerves that send info to & fro CNS
Simple spinal reflexes
reflexes that travel through spinal cord only.. do not reach the brain
Where do the endocrine & nervous systems meet?

2 major groups of hormones?
Steroid hormones & protein hormones
Steroid hormones
Hormones that target cells & have direct effect on DNA of the nucleus
Protein hormones

How do most hormones effect cell activity?
By altering rate of protein synthesis
